Patented Feb. 25, 1919.

Application filed January 21, 1913, Serial No. 743,270. Renewed January 4, 1919. Serial No. 269,657.

To all whom it may concern:

Be it known that I, JOHN HAYS HAM- MOND, J r., a citizen of the United States, re-

siding at Gloucester, in the State of Massa- .distance, and relates more particularly to systems in which pneumatic or hydraulic,

machinery for operating the steering gear and engines of torpedoes and other vessels and the like, is controlled by radiant energy transmitted from a distant station.

In the accompanying drawings Figure 1 shows a diagrammatic view of one form of ,a receiving station on my system employing electric and pneumatic appa- Fig. 2 gives a more detailed view, partly diagrammatic, of part of the apparatus on my system on board a torpedo or some other vessel.

In Fig. 1, A is an antenna connected to earth E through the inductance coil L and variable condenser C, and inductively cou pled to the oscillation circuit L C by means or the coils L and'L C being a variable condenser, and the circuit L. C being in tune with the antenna circuit. D is a stopping condenser and R a rectifier, by means of which unidirectional current impulses are supplied to the coil L which is inductively coupledto the oscillation circuit L C consisting of the coil L and the variable condenser C this latter oscillation circuit being tuned to the group frequency or amplitude variation tion. D is a stopping condenser and R a rectifier, by means of which unidirectional currents are supplied to the sensitive relay K, which is connected with the battery B equency of the. transmitting stavalve 5 under certain circumstances, as will hereafter be described.

In Fig. 2, 5 is a rotary cylindrical valve operated by the electromagnet M. This valve, instead of having electrical contacts upon it, has ports or openings, such as 19, 20, 21 and 22, which control the flow of a fluid. The electrofnagnet M moves the valve 5 step by step. 1 The ports or openings of the outer air. There are other similar sets of ports in the valve, which are not shown.

vPipes 14, 15, 16 and 17 can be, operatively connected with ports 19, 20, 21 and 22, re-

spectively. Pipes 14 and 17 lead to the openi 1ngs or ports 30 and 28, respectively, in

' cylinder 4, and pipes 15 and 16 lead to the openings 27 and 29, respec;ively, in cylinder 3'. The spring 31 tends to move the piston 3 toward the openings 27 and 29, and the opening or port 23 is made small so that air or other fluid can enter and escape through it only slowly, and any movement ofthe "piston 3 toward the right will therefore be retarded. Spring 32 and opening 24 in cylinder4 have similar functions to spring 31 and opening 23 in cylinder .3. Piston rod 3 is operatively connected with the ports 10 and 11, Which'open and close the pipes 25 and 26, respectively. Pipe 25 connects pipe 15 with cylinder 1, and 26 is an exhaust pipe leading from cylinder 1 to the outer air.

Piston 4 is connected to piston rod 4", which is operatively connected with ports 12 and 13, which open and close the pipes 34 and 35, respectively. Pipe 34 connects pipe 17 with cylinder 2, and 35 is an exhaust pipe leading from cylinder 2 to the outer air.

Cylinder-1,,by means of the piston 1 and piston rod 1", is operatively connected with the helm 6, and cylinder 2, by means of the piston 2 and piston rod 2", is also operatively connected with the helm 6, which is connected with the rudder, the latter not about a fixed pivot 6 and the spring back to their original positions.

'36, which is normally working fluid, is admitted to the .which leads to the auxiliary pistons-N,

against open valve 44. The momentum of the helm tends to keep the helm 6 in a central position.

' The bar 48 is attached to the helm 6 and has projecting end pieces 46 and 47.. lli-pes 40 and 45 are connected with the tank T or other source of supply of the working fluid. Valve 39 opens and closes pipe 40, and is operated by means of the bent lever 38. Pivoted on this bent lever is a movable piece held against a stop 49 by the spring 37. When end piece 46 is moving to the right, piece 36 is momentarily depressed, but as soon as 46 has passed it is restored to its original position by spring 37. When, however, 46 is moving to the left and strikes 36, the latter presses against stop 49 and causes thebent lever 38 to open valve 39.. The momentum of the helm and its attached mechanisms will then carry the bar 48 and its end piece 46 on until the piece 36 is pushed so far to the left that piece 46 can move over and past it, when the bent lever 38 and valve 39 will drop back to their original positions.

When valve 39 1s open, the air or other Pipe 8 Piston N then operates the rotary valve 5 and causes the latter to move to a neutral posi-' tion and so stops the whole system.

Valve 44 opens and closes pipe 45 and is operated by means of the bent lever 43. Pivoted on this bent lever is a movable piece 41, which is normally held against a stop 50 by the spring 42. When end piece 47 is moving to the left, piece 41 is momentarily pushed aside, but as soon as 47 has passed, it is restored to its original position by spring 42. When, however, 4'6 is moving to the right and' strikes 41, the latter presses stop 50 and causes the bent lever to and its attached mechanisms will then carry the bar 48 and its end piece 47 on until the piece 41 is pushed so far to the right that piece 47 can move over and past it when the bent lever 43 and valve 44 will drop -When valve 44 is open, the air, or other working fluid is admitted to the pipe 8 which leads to the auxiliary piston N. Piston N then operates the rotary valve 5 and causes the latter to move to a neutral position and so stops the whole system.

In this way the above described. mechanism acts as a center stop, to hold the helm and rudder in a central position when they return from a port or starboard position.

" When compressed air is. used as the work ing fluid, the method of operation of my system is as follows :In Fig. 2 the electro magnet M has caused the valve 5 to rotate into a position where port 22 connectsthe suppl pipe 18 with the pipe 17 leading to the cy inder 4, and where the port 21 connects exhaust pipe 16 leading from cylinder 3 to the outer air. The exhaust pipe 14 from cylinder 4 is closed. Compressed air will enter cylinder 4 through pipe 17 and port 28 and piston 4 will begin to move to the left. But it can move only slowly, as the air to the left of the piston will be compressed and cannot escape rapidly through the small opening 24. When piston 4- finally reaches the left end of its stroke, it will cause port 13 to open and port 12 to close. Port 13 connects pipe 17 with pipe 34, thus allowing the compressed air to enter cylinder-2, and as the exhaust pipe 35 is closed, the piston 2 will be moved toward the left and will move helm 6 to the left.

If is desired to stop the helm at any particular position, the electromagnet M should be energized by another impulse, thereby causing the rotary valve 5 to move to a neutral position where none of its ports will be connected with pipes 14, 15, 16. and 17. The intake and exhaust pipes of cylinders 4 and 2 will therefore be closed, and pistons 4 and 2" will be held stationary; the whole system will be locked and the helm and rudder will be held in whatever position they happen to occupy.

When it is desired to move the rudder back to its central position, another impulse should be sent, energizing magnet M, and causing the latter to rotate valve 5 to its next operative position, where ports 19 and 20 are connected, respectively, with pipes 14 and 15. Compressed air will pass from'supply pipe 18 through port 20, pipe 15 and port 27 into cylinder 3, thus moving piston 3 to the right; and at the same time cylinder 4 will exhaust through port 30, pipe 14 and port 19, and piston 4 will be pushed to the right by spring 32. When piston 4 moves to the right, port 12 will be opened, so that cylinder 2 can exhaust through pipe 35.

As piston 3 moves to the right, exhaust port 11 will be closed and intake port 10 will be opened, thus allowing compressed air to enter cylinder 1 through pipe 25 and causing piston 1 to move toward the right. Helm 6 will therefore be moved to the right, toward its central position. As the proj ecting piece 47 at the end of bar 48 moves to the right, it will engage with piece 41 and so cause the bent lever 43 to open valve 44 and permit compressed air to pass through pipes 45 and 8 to pneumatic piston'N. Piston N will cause rotary valve 5 to move to: a neutral position and thus lock the whole system, but the inertia of the helm and the attached apparatus will cause contact piece 47 to move far enough to the right to pass over movable. piece 41, as previously described, and the helm will reach its'central position before stopping' In this way, the

rudder will be caused to stop automatically 1:1

causes it to rotate valve 5 in a central position; .and the same series of operations can be made to occur if the rudder moves in the opposite direction.

The position of the'helm can be regulated as desired. For instance, if it is to be moved a little to the left, compressed air is admitted to cylinder 2, as above described, and after piston 52 has moved the helm 6 to the angle desired, another impulse is sent from the transmitting station, thus energizing the electromagnet M and causing it to rotate the valve 5 to a neutral position. If then it is desired to move the helm still more to the left, the electromagnet M is energizedthree times in rapid succession, with the following results: Theifirst time it is energized,..it will cause the valve 5 to move to the operative position where compressed air is admitted to cylinder 3 and exhausted from cylinder 4, but as pistons 33 and 4* can both move only slowly, owing to the slow passage of air through the small openings 23 and 24, respectively, they will not have moved far enough to cause compressed air to be admitted to cylinder 1 and exhausted from cylinder 2 before the second impulse energizes electromagnet M and to a neutral position. The third impulse will then energize M again and cause it to rotate valve 5 to an operative position where compressed air is admitted to cylinders A and 2 and exhausted from cylinders 3 and 1, and valve 5 can be kept in this position. until'the helm is moved still farther to theleft to any angle desired. 7

A similar course of procedure is followed with the opposite operative positions of valve 5 when it is desired to move the helm to the right, and it is possible,'as shown, to cause the rudder to assume any angle de- I do not limit myself to the use of air as a working fluid, but may use any other suitable gas or any suitable liquid,. nor do I limit myself to a steering device for torpe does or other vessels, but may put my invention to any use desired; and in general I do not confine myself to the particular apparatus and mechanisms here shown, but va rious changes and modifications, within the capacity of those skilledin the art, may be made in the particular apparatus shown and described herein, without departing from the spirit of my invention," provided the means set forth in the following claims be employed.
